A prospective study of trephined bone grafts of the tibial shaft and iliac crest.

Autogenous cancellous bone grafting is a common procedure in maxillofacial surgery. Open harvesting usually results in a long scar and considerable morbidity, but harvesting using a trephine can be done through a smaller scar with minimal morbidity. The commonly used anatomical areas for trephine harvesting are the iliac crest and the tibial shaft. A prospective study was carried out in 30 patients to compare the technique and the morbidity as perceived by patients using a visual analogue scale (VAS) and by an independent observer. The surgical anatomy and techniques are described. The results show no significant difference between the two groups, but the tibial trephine procedure is easier, quicker, and causes less blood loss. The total scores for pain and difficulty in walking were much less for tibial than that for the iliac grafts.

An audit of oral and dental health regimens practised in the management of oropharyngeal cancer.

The purpose of the present study was to find out what preventive care was offered to patients after radiotherapy, particularly if they were dentate. As the mean age of the population increases and the number of people who retain at least some of their teeth into old age also rises, it is likely that more and more people with a diagnosis of oral cancer will be dentate. The incidence of oropharyngeal cancer has also started to increase recently and is affecting more young and dentate people. It is of paramount importance to provide comprehensive management for these patients, not only to remove the disease and reconstruct the defect, but also to provide the patient with the opportunity of experiencing a good quality of life by having a comfortable mouth after treatment. A questionnaire was sent to all senior fellows of the British Association of Oral and Maxillofacial Surgeons (BAOMS) and the results analyzed. The results of this survey show that improvements could be made if some simple preventive measures were instigated in the early stages of treatment.

The galeo pericranial flap in oropharyngeal reconstruction.

Flap reconstruction of the oropharyngeal region using a galeo pericranial flap was performed in 26 patients. This paper describes the anatomy, technique and discusses the outcome of the surgery showing that all flaps but one had good long term vascularity. Good access to all areas of the oropharynx was possible, the flap length was up to 20 cm and width up to 15 cm. Complications were minimal but included a tendency to form intra oral fibrous bands, patchy alopecia of the composite using outer plate of calvarium. The galeo pericranial flap is a valuable technique and can be used successfully in suitable cases.

Morphometric analysis of orbital, buccal and subcutaneous fats: their potential in the treatment of enophthalmos.

Retro-orbital fat volume reduction has been reported in patients with enophthalmos but could be restored by a suitable fat autograft. Buccal and subcutaneous adipose tissues were identified as possible donor sites. Samples of these and of orbital fat were obtained from fresh cadavers, and the relative volumes of collagen and of endothelial cells and the numerical density of mast cells were compared since these might influence graft survival. The results demonstrated strong similarities between orbital and buccal fat which were significantly different from subcutaneous fat. It was concluded that the buccal fat pad would be a more suitable donor site than subcutaneous adipose tissue to replace orbital fat loss and that its use merits further investigation.

Facial scoliosis--a diagnostic dilemma.

Facial scoliosis may be caused by frontal plagiocephaly or muscular torticollis. Determining the correct cause has implications for patient management. Past confusion in the literature has led to difficulty in determining appropriate treatment plans. The correct diagnosis may be readily obtained by using a series of clinical and radiological features peculiar to each condition. Four cases are shown demonstrating these diagnostic features.

Experience in the use of calvarial bone grafts in orbital reconstruction.

It is now accepted that calvarial bone is a suitable material for grafting in the facial area. From an extensive experience of using calvarial grafts in all regions of the face, the orbit has been singled out for this study. A group of 222 patients who underwent 279 calvarial grafts has been examined. The majority of patients had post-traumatic or congenital deformities. Reconstructions were performed with split-thickness cranial bone grafts and in some cases, the full-thickness of the cranium was used. The follow-up period ranged from 3 months to 4 years with an average of 20 months. After the first operation, 86% of the sample attained satisfactory aesthetics on clinical examination. There were 13 (4.6%) complications, most occurring during harvesting full-thickness calvarial grafts. From this study it is seen that orbital reconstruction can be performed using calvarial bone to obtain satisfactory aesthetic and functional results. This can be accomplished with minimal donor site morbidity.

Midfacial fractures and the eye: the development of a system for detecting patients at risk of eye injury--a prospective evaluation.

Midfacial trauma is often complicated by ocular disorder. A scoring system has been devised to help the maxillofacial surgeon identify patients who warrant referral to an ophthalmologist. A prospective pilot study was carried out on 100 patients with midfacial fractures to evaluate the effectiveness of this system in clinical practice. The sensitivity value was 94.4% and the specificity value was 89%. Only 1 patient, who clinically warranted referral to an ophthalmologist, was missed by the system whilst 9 others were incorrectly classified as warranting referral. The results of this evaluation demonstrate the competence of the system.

Transconjunctival approach to the infraorbital region: a cadaveric and clinical study.

The surgical anatomy of the transconjunctival approach to the infraorbital region was studied using fresh cadaver dissection, histological examination and in the clinical situation. The existence of a periorbital envelope which separates the orbital fat from the orbital septum, and a potential postseptal space was noted. Reference to these anatomical features could not be found in the literature. The postseptal space was used to gain access to the infraorbital rim and the orbital floor. Wire and plate osteosynthesis of the infraorbital rim and exploration and reconstruction of the orbital floor were performed without fat herniation into the operative field. Access was adequate for these procedures and lower lid malposition was not observed as a postoperative complication.

A comparison of imaging techniques with surgical experience in orbital injuries. A prospective study.

The aim of the study is to compare the effectiveness of computerised tomography (CT) and magnetic resonance (MR) imaging in diagnosing herniation and entrapment of orbital soft tissues in orbital fractures. 15 consecutive patients with clinical signs and symptoms of medial orbital wall injury were examined with CT and MR. The data were subsequently compared with the findings of the surgical exploration with regard to the extent of the wall fractures, the presence of soft tissue herniation and its entrapment. CT and MR were equally accurate in demonstrating or excluding orbital wall fractures but both modalities slightly underestimated their incidence. CT and MR underestimated the actual incidence of soft tissue herniation and entrapment when compared with the surgical findings but the extent of soft tissue herniation and entrapment were demonstrated more clearly by MR than by CT scanning. MR imaging when available should therefore be used as the initial imaging modality and CT held in reserve for confirmation as positioning in the MR unit is easier and more comfortable for recently injured patients who may well have other injuries.

Correction of facial deformities in patients with mild bleeding disorders: a report of three cases.

A bleeding diathesis need not be a contra-indication to elective surgical correction of facial deformities. Preoperative haemostatic assessment and management of haemostasis during and after surgery is described. Two cases of mild von Willebrand's disease and one case of factor XI deficiency who successfully underwent orthognathic surgery for the correction of facial deformities are reported.

Cross-match requirements in orthognathic surgery: an audit.

A retrospective audit was undertaken of the value of routine cross-matching of blood for patients undergoing orthognathic surgery at Canniesburn Hospital, Glasgow. Overall, routine cross-matching of blood was wasteful of resources for all but the more major types of osteotomy procedure: Le Fort III, Le Fort II, malar osteotomies requiring a bicoronal flap and bimaxillary osteotomies. The study has financial implications regarding the proper use of cross-matching in selected patients undergoing elective orthognathic surgery. A blood ordering tariff has been suggested for the various procedures studied.
